Saṃjñā–Chāyā Upākhyāna: Sūrya-tejas, Substitution, and the Birth of Manu, Yama, and Yamunā
संवर्तुलं तु तद्रूपं दृष्ट्वा संज्ञा विवस्वतः । असहंती ततश्छायामात्मनस्साऽ सृजच्छुभाम्
saṃvartulaṃ tu tadrūpaṃ dṛṣṭvā saṃjñā vivasvataḥ | asahaṃtī tataśchāyāmātmanassā' sṛjacchubhām
Seeing that overpowering, blazing form of Vivasvān, Saṃjñā could not endure it; therefore, from her own being she created an auspicious shadow-form (Chāyā).
Suta Goswami (narrating the Purana account to the sages, as typical of the Shiva Purana’s discourse frame)
Tattva Level: pasha
Shiva Form: Kālāntaka
Sthala Purana: The adjective saṃvartula (‘like the Saṃvarta fire of dissolution’) evokes pralaya-imagery rather than a specific liṅga-site; it functions as a cosmological simile for unbearable tejas.
Role: creative
Cosmic Event: Pralaya-simile (saṃvarta-like blazing form)
The verse shows how finite beings cannot directly endure overwhelming radiance; a “shadow-form” symbolizes the mediated experience of reality under limitation (pāśa). In Shaiva Siddhanta terms, the soul’s capacity is gradually purified through discipline and grace until it can abide in higher light.
Like Saṃjñā needing a bearable form, devotees approach the Supreme through accessible manifestations—Saguna Shiva and the Linga—so the mind can steadily contemplate the infinite without being scattered, and then mature toward deeper realization.
It implies gradual approach through steady sādhanā: daily japa of the Panchakshara (“Om Namaḥ Śivāya”), Linga-dhyāna, and purificatory observances (e.g., Tripuṇḍra with bhasma) to build inner capacity for higher spiritual “radiance.”
